Yes ... if you were paid to do it and that is your profession or you are in school for it, I'd say it's OK to share a few images of your models. I would suggest that you should not post images of your actual clients without specific written permission to do so, since this is a public forum ... otherwise, it could open up some serious legal issues for you.
We are primarily a "fashion" site, we don't actually seek out artists that do only prom and bridal ... but posting a few of those types of images is not forbidden.
